5.2 Safety instructions regarding in-
stallation, operation, cleaning and
maintenance
DANGER Risks for children and people
with reduced physical, sensory or mental cap-
abilities or a lack of knowledge.
Unit may only be installed, commissioned,
cleaned and maintained by persons who can
safely recognise and avoid the risks associated
with this work.
WARNING Risk of injury due to suction
from unit and rotating impeller.
Hair, clothing, jewellery etc. may be pulled into
the unit if you get too close to it.
During operation, always keep far enough away
to prevent this from happening.
WARNING Risk of injury if foreign objects
are inserted into the unit.
Do not insert any objects in the unit.
WARNING Risk of injury when working at
heights.
Use appropriate climbing aids (ladders).
Stability should be ensured, if necessary have
the ladders steadied by a 2nd person.
Ensure that you are standing securely and can-
not lose your balance and that there is no one
under the unit.
NOTICE A fan that is not installed correctly
may result in non-intended operation or im-
permissible operation.
Operation is only permissible when installed in a
WH... wall sleeve and in the correct installation
position, with terminal compartment cover fitted
and external protective grille.
The fan may be operated only if the protection
against accidental contact with the impeller is
guaranteed to be in accordance with DIN EN ISO
13857.
WARNING Risk of injury and health risk
in the event of changes or modifications or if
components which are not permitted are
used.
The unit may only be operated with original com-
ponents. Modifications and alterations to units
are not permitted and release the manufacturer
from any guarantee obligations and liability.
DANGER Risk of death from carbon
monoxide when operating with air-ventilated
fireplaces.
The maximum permitted pressure difference per
residential unit is 4 Pa. The consent of a profes-
sional chimney sweep is needed in all cases.
Ensure sufficient supply air intake during opera-
tion with an air-ventilated fireplace.
DANGER Danger of electric shock when
operating a fan which is damaged or not fully
mounted.
Before taking off the terminal compartment cover,
shut down all supply circuits (switch off mains
fuse), secure against being accidentally switched
back on and position a visible warning sign.
Only operate the fan when it is completely in-
stalled.
Do not commission a damaged unit.
DANGER Danger if the relevant regula-
tions for electrical installations are not ob-
served.
Before installing the electrics, shut down all sup-
ply circuits, deactivate the mains fuse and secure
it so it cannot be switched back on. Attach a
warning sign in a clearly visible place.
Be sure to observe the relevant regulations for
electrical installation; e.g. DIN EN 50110-1. In
Germany, particularly observe VDE 0100, with
the corresponding sections.
A mains isolation device with contact openings of
at least 3 mm at each pole is mandatory. In gen-
eral, use earth leakage circuit breakers.
Only connect unit to a permanently wired elec-
trical installation and with 1.5 mm² cables of type
NYM-O or NYM-J.
The unit may only be operated using the voltage
and frequency shown on the rating plate.
The degree of protection stated on the rating
plate is only guaranteed if installation is under-
taken correctly and if the connecting cable is cor-
rectly guided through the cable grommet. The
grommet must tightly seal the cable sheathing.
Do not install switches and control components in
the shower area – no splash water protection.
With protection class I, connect the PE conductor
and check the connection.
